Comments from some of those who selected OmniGraffle as one of their Top Tools
“brilliant for diagramming. I’m visual/conceptual and it works the way I want and makes my output look good (I went back and recreated old diagrams just because it was so fun; when’s the last time you said that about productivity software?)” Clark Quinn
“OmniGroup’s diagramming software is for much more than drawing diagrams. It’s useful for doing concept maps, outlining chapters in a book, illustrating statements and proofs of theorems — I even used it to redesign my kids’ playroom at home. Better than a paint program and way simpler than something like Adobe Illustrator.” Robert Talbert
